PTA EXAM NPTE (MUSCULOSKELETAL)
QUESTIONS WITH CORRECT ANSWERS
Hip illiofemoral ligament CORRECT ANSWER Extends from anterior inferior iliac spine
to intertrochanteric line of femur. LIMITS excessive hip extension Y fan shape

Hip Pubofemoral ligament CORRECT ANSWER Extends from Pubic portion of the rim
of acetabulum to the neck of the femur. LIMITS excessive abduction and extension

Ischiofemoral ligament CORRECT ANSWER extends from the iscial wall of the
acetabulum to the neck of the femur Limits EXT and IR and reinforces the articular
capsule

Acetabular labrum CORRECT ANSWER Fibrocatilaginous rim attached to the margin of
the acetabulum

ATP-PC system CORRECT ANSWER High intensity short duration exercise such as
sprinting 100 meters. Phosphocreatine decomposes and releases a large amount of
energy. Provides energy up to 15 seconds

Anaerobic glycolysis CORRECT ANSWER High intensity short duration activities such
as sprinting 400-800 meters. Stored glycogen is split into glucose and through
glycolysis split again into pyruvic acid to form ATP 30-40 seconds of muscle contraction

Aerobic Metabolism CORRECT ANSWER Low intensity long duration exercise such as
running a marathon. Oxygen yield the most ATP but requires complex chemical
reactions through oxidation of food.

Synarthroses joint (fibrous) joint classification CORRECT ANSWER Fibrous joints
composed of bones united by fibrous tissue and are non synovial. movement is minimal

Sutre (synarthroses) CORRECT ANSWER Union of 2 bones by a ligament or
membrane (ex-sagittal sutre of skull)

Gomphosis (synarthroses) CORRECT ANSWER 2 bony surfaces connect such as a
peg in the whole ex (tooth in a socket)

Syndesmosis (joint classification) CORRECT ANSWER Bone connected to bone by a
dense fibrous membrane or cord

Amphiarthrosis (cartiliginous joint) CORRECT ANSWER Cartiliginous joints have
cartilage or fibrocartilage that connects one bone to another. slightly moveable joints

Symphysis (ampiarthroses) CORRECT ANSWER located in the midline of the body, 2
bones with hyaline cartilage

Diarthroses (synovial joints) CORRECT ANSWER Provide free movement between
bones and have 5 distinguishing characteristics, Joint cavity, articular cartilage, synovial
membrane, synovial fluid, and fibrous capsule most complex and vulnerable

Uniaxial-one plane (hinge/Pivot)
Biaxial - 2 planes (condyloid, saddle)
Multiaxial- 3 planes (plane, ball and socket)

Shoulder Glenoid labrum CORRECT ANSWER firocartiliginous structure that depends
the glenoid fossa and increases the size of the articular surface

Shoulder joint capsule CORRECT ANSWER Arises from the glenoid fossa and the
glenoid labrum to blend with the muscles of the rotator cuff
